PUMPING APPARATUS.

Application filed September 4, 1923. Serial No. 660,723.

To all whom it may concern:

Be it known that'I, CLARENCE WARNER, a citizen of the United States of America, residing at Dayton, county of Montgomery, and State of Ohio, have invented certain new and'usefulImproVements in Pumping Apparatus, of which the following is a full,

' clear, and exact description.

This invention relates to pumping systems which includes. pressure tank in which water is stored under. .pressure, so that a quantity of water may be used before it is necessary to operate the 'pump to sup- More particularly, the present invention relates to devices of the type described and illustrated in. the co-pending application of Buvinger, Warner and Smith, Serial No. 628,799, filed March 30, 1923, which includes an air charger for providing a'storage tank with air under pressure without requiring the use of an auxiliaryair pump,

and. without discontinuing the water supply, the water pump itself being used as the source of pressure supply for causing air to be forced into thecstorage tank under pressure.

It is an object of the present invention to provide an air chargerapparatus which will be durable and reliable, and which will tend toward compactness and reduction of the number of parts.

In the present invention, there is provided, a main duct connecting a source of water supply with a water pressure storage I tank and 'a duct b -passing a portion of the main duct. The y-pass duct is controlled so that air is permitted to accumulate therein and when it is desirable to force air into the storage tank, the by-pass duct is placed in parallel with the main duct whereby some of the water, flowing from the source of supply to the tank, will flow through the by-pass duct and force. the air accumulated therein into the tank. One of the objects of the present invention is to cause the air from the by-pass' duct to be readily forced into the tank. One manner of accomplishing this object. is to restrict the flow of water through thatportion of the main duct which is by-passed by said by-pass duct whereb a large portion of the water flowing to t e tank will flow through the by-pass duct.

Otherv and further objects and advantages of the present invention will be apparent from the following description of a preferred embodiment thereof, reference being made to the accompanying drawings.

In the drawings:

Fig. 2 is a top plan view thereof.

Fig. 3 is a fra mentary view, partly in section, showing tl ie auxilia'rytank open to atmosphere and drain, but closed to the water supply.

Fig. 4 is a sectional view showing the auxiliary tank open to the water supply but closed to atmosphere and drain.

Fig. 5 is a view of the restricting means in open position.

ZFig. 6 is a view of the same in closed position. 2

Referring to the drawings, a pump 20 is connected with a source of water supply by pipe 21 and with an air charger unit, designated as a whole by numeral 25 by pipe 22. The water. and air outlet connections between the air charger 25 and a storage tank 100 are provided by 1ping 26. The tank 100 is provided with ,a

sight glass 101 for indicating the water adapted to be rotated, as indicated by.

dotted lines in Fig. 2, and within-which air for charging. the pressure tank 100 can be collected. Valve member 28 is secured to the outer surface of tank 27 and is provided with a central passage 29 which registers with an opening in the wall of the tank and also passages 30 and 31-set at substantially 90 degrees with respect to one another, which are adapted to register with openings 32 and 33 respectively in the tank 27. A valve member 34 is secured to the outer surface of tank 27 directly opposite valve member 28, and is provided with a central passage 35 registering with an opening in the tank 27, and also passages 36 and 37, set at substantially 90 degrees with respect to one another, which are adapted to register with openings 38 and 39 respectivein the tank 27. A pipe 40 which extends through tank 27 connects passages 29 and 35 and forms a portion of the main duct or passage between the pump and tank. Secured to the end of pipe 22 is a valve body 41 provided with a chamber 42 in alinement with the pipe 22, and with passages 43 and 44 set at substantially 180 degrees. body 41 is adapted to receive valve member 28 and provides a seat therefor. When the tank 27 is in the position shown in Fig. 3, passages 30 and 44 register to connect the tank 27 with drain, and the passage 31 does not register with the passage 43. When the tank 27 is in the position shown in Fig.

4, passages 31 and 43 register thus connecting the tank 27 with the passage 42, and passage 30 does not register with passage 44 so that water cannot escape from the tank 27 through pipe 45. A check valve 46 is threaded into the valve body 41 for preventing water flowing back-from chamber 42 into pipe 22. Drain 45 may lead'back to the source of water sup-ply or to a waste sewer.

A valve body 50 is attached to piping 26 and provides a seat for valve member 34.

Valve body 50 is provided with a chamber- 51, in alinement with pipe 26, and with passages 52 and 53 set at substantially 180 degrees. When tank 27 is in the normal position shown in Fig.3, passages 31 and 37 are closed, and passages 36 and 53 and pipe- 55 connect tank 27 .with an air inlet controlled by check valve 54. Supporting arms extend from opposite sides of the valve bodies 41 and 50, and in the present disclosure are disposed at substantially 45 degrees with respect to the plane of pipes 26 and 22. The outer ends of thesearms 60 are connected by bolts 61 which pass therethrough. Springs 62 which surround the lower ends of these bolts 61 and bear against the arms 60 carried by valve body 41, and the washers 63 are held in position-by nuts 64 threaded on bolts 61. The springs 62 tend to maintain the valve membodies 41- and 50,- respectively, when the tank 27 is rotated. Bolts 61 limit the movement of tank 27 to substantially 90 degrees,

Valve comprises a rod 66 suspended from the up-. per wall of valve body 50 centrally of passage 35, with a pin 67 passin therethrou h ad acentthe lower end of t e rod. Su

stantially semi-cylindrical shaped restricting members 68 and 69 which fit over the top of passage 35 are held down by a headed:

pin 70 carried by valve member 34 and are a spring 71 the opposite ends of which are held in contact with the shank ofpin 70 by secured to said restricting members. Members 68 and 69 are provided with notches,

gage the notches 72 and 73, and the restricting members 68 and 69 will be drawn toward each other by the spring71, thereby restrictin the flow of water through passage 35 w ereby a large portion of the. wa ter flows through tank 27 The operation of the air charger will be as fo11ows: U

With the air charger inits normal position, as shown in Fig. 3, the tank 27 will be filled with air, being open to atmosphere through air valve 54, pipe 55, passage 53, passage 38'and open to drainthrough passage 30, passages 44 and 45. Water will flow from the pump '20,through the main duct including pipe 22, valve 46, chamber 42, pipe 40, chamber 51, piping 26 into the storage tank 100. The restricting meanswill be in the position shown in Fig. 5, in which. positionthe maximum amount of water 1s dication that water should :be pumped into bers 28' and 34 seated within the valvetank 100; and, when'the glass 101 isentirely filled with water, this is an indication that it is necessary to operate the air charger in. order to maintain the necessary amount of air for pressure storage in the tank 100;

Assume that the'glass. 101 is entirel filled with water, thus indicating that t e air charger should be operated to force air into the tank 100, and assume that the tank 27 is filled with air. The tank 27 is rotated in a clockwise direction to the dotted line position as viewed in Fig. 2, until its movement is stopped by contact with bolts 61, at which time the tank 27 will have rotated substantially 90 degrees. This rotation of the tank 27 rotates the valve members 28 and 34,

thereby closing the tank '27 to atmosphere and to drain, but opening it to the pump 20 and tank 100. Water will then flow from pump 20, through pipe 22, valve 46, chamber 42, passage 43, passage 31 into tank 27 and out through passage 37, passage 52, chamber 51, piping 26 into the tank 100, passages 43, 31 tank 27, passages 37 and 52 providing a duct which by-' passes that portion of the main duct including passage 29, pipe 40 and passage 35. Thus the airwithin the tank 27 will be forced into the tank 100. However, the restricting means will be in the position shown in Fig. 6, and therefore only a small amount of water will flow through pipe 40 and passage 35 into the tank 100. When the pressure in the system reaches a predetermined value,the operation of the pump 20 will be discontinued by action of the pressure operated switch heretofore mentioned.

The tank 27 may then be returned to the position shown in Fig. 3 to permit the tank to drain and be 'filled with. air ready for the next air charging operation, and for permitting'the maximum amount of water to flow through passage 35.

While the form of mechanism herein shown. and described. constitutes a preferred embodiment of one form of the invention, it isto be understood thatother forms 'might be adopted and various changes and alterations made in the shape,'size, and proportion of the elements therein without departing from the-spirit and scope of the invention.- i
